One of our favourite soundproofing material is Quiet Batt 30. It’s designed for use in both interiors and exteriors. Thanks to its specific formula, not only it reduces noise, but provides excellent thermal insulation as well. When it comes to noise reductions – Quiet Batt out performs typical fiberglass. Since we use only quality products – we love to use it in our own soundproofing solutions. London Soundproofing Solutions – we know our job like a back of our hands!
